I just taught myself to paint interior walls and painted a room! Still drying so looks a bit splotchy and lighter/more gloss than it will (bits right near ceiling/corners/outlets that were cut in by brush before rolling are closest to the real color) but really happy with it already, first time in my adult life moving in to a place I have free reign to paint so feels extra special to banish the off-white that's been my every wall living in property managed apartments through my third and fourth decades...
